David Lonnecker of San Diego, California, used to have a Dodge pickup with a built 5.9L Cummins. He loved the engine but has always been partial to classic Ford trucks. So like a growing number of diesel enthusiasts, he decided to build his own truck—the way he wanted it. Before David contacted us a few months back to be in the Readers’ Diesels section. With one look, we decided he needed three pages in Diesel Power to highlight the restoration of his ’70 Ford F-250 (with 80,000 miles). He told us people in newer trucks often come up to him at stoplights or while he’s parked to ask questions—or just stare. This proves a cool diesel truck is still possible on a budget. Originally, these older crew cabs were built for specialized work detail. Today, David mostly uses his pickup for running the family to the beach or for off-roading in the desert. The four-cylinder 4BT Cummins diesel engine was taken from a ’90s bread truck with 120,000 miles on it. David put the intercooler between the radiator and engine and then plumbed the piping himself. He also added an electric fan, which freed up horsepower and kept the engine from ever coming close to overheating. The hydroboost brake system is from Performance Online (POL), and it runs off the power steering pump. The serpentine belt system makes maintenance much easier than working on the original 390ci (6.4L) gas big-block. Fuel economy has also increased by more than 50 percent compared to the sparker. The truck now gets around 25 mpg.

The fuel screw and star wheel were both cranked in a few turns, too. Other features include 40hp injectors and a new mechanical lift pump. This engine also has a mechanical fuel shutoff, so electricity is not needed to start or stop the engine. Although it’s never been on a dyno, 200 hp and 450 lb-ft is expected.

Autofab in Santee, California, helped David with the suspension, engine mounts, and frame-off restoration. The twin I-beam front has kingpins instead of ball joints. It also has twin piston brake calipers. Autofab added the new coils and built the new radius arms to restore the suspension geometry. Since two-wheel-drive Ford trucks of this vintage steer from behind the tires, the engine was set up to clear the linkages.
